To all whom it may concern:

Be it hnownthat I, DANIEL N. Baxrnn, a citizen of the United States,residing at Wichita, in the county of Sedgwick and of Kansas, haveinvented certain new and useful Improvements in Boiler-Cleanand Idodeclare the following to be a clear, and exact description of the inon,such as will enable others skilled in re art to which it appertains tomake and the same,

This invention relates to improvements in boiler cleaners.

The object of the invention is to provide an improved construction ofboiler cleaner which may be used in connection with any form of boilerwhereby the mud and other impurities may be removed from thejwater andsteam and the latter applied to the cylinders in a dry clean condition.

With the foregoing and other objects in View, the invention consists ofcertain novel features, of construction, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings, Figure l is a side view of a boilershowing the application of the invention thereto. Fig. 2 is a plan viewof the same. Fig. 3 is .a vertical section through the boiler on theline Of 1- i I Tvfy improved boiler cleaner is herein 'hdwn as appliedto a locomotive boiler and sists of two settling drums or tanks 1, whichmay be of any suitable size according E the size of the boiler to whichthey are applied. The cylinders or tanks 1 may be arranged at anysuitable point on the boiler, below the water line, and when used inconnection with locomotive boilers are preferably arranged on each sidethereof immedi ately below the running boards as shown. The drums ortanks 1 are connected at one end and near their upper sides with theboiler at about the water line therein by water circulating pipes 2 inwhich are arranged valves 3. The drums 1 are connected at their oppositeends and near their upper sides by returnpipes lto the mud ring of theboiler. The return pipes i have ar ranged therein cut ofl' valves 5 andunions 6' The drums l are connected at sides and preferably near one s 7of '*.on--

as shown. tta'r u through.

connected to the steam dome 9' of the boiler.

The pipe 8 has arranged therein a cut off valve 11 and a union 10. Inthe lower side of each of the drums 2 is arranged a blow off pipe 12said pipes having valves 13 arranged therein as shown. valves in thesteam pipe 8 and in the blow off pipes 12 themud and sediment is blownout of the drums by the steam passing there- The drums 2 are connectedby injectingpipes 14 to the water tank in the engine tender or to anyother source of water supply whereby feed water is supplied through thedrums to the boiler. In the pipes 1d are arranged cut off valves 15wherebythe flow of water through the pipes is controlled. The pipes 14:are also provided with check valves 16 whereby the water in the drums isprevented from being forced back into the supply tank.

\Vhile the invention is herein shown and described as being applied to alocomotive boiler it is obvious that the same may be readily applied toany form'of steamboiler for the purpose of cleaning or removing Byopening the ran RATENT OFFICE.

therefrom mud scale, and all other form of sediment or impurities.

In the operation of the device the cold feed water enters the drums bypipes 14 and mingles with the hot water coming from the boiler by pipes2; the feed water becomes heated and the sediment of the hot water isdeposited in the drums and blown off. The heated feed water then passesby the return pipes 4, to the coolest part of the boiler, thus promotingcirculation. The heated water'in the'boiler largely rises along thesides of the boiler, carrying scum and sediment with it, and by havingsymmetrically disposed drums on each side of the boiler the feed wateris more uniformly heated and the scum and deposits are more uniformlyremoved from the boiler and deposited in the drums, than if only asingle drum were used, andif one drum should get out of order the otherwould be effective.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departingfrom the principle orsacrificing any of the advantages of the invention as. defined in theappended claim.

What is claimed The improved boiler cleaner for locomotive boilersherein described and shown. consisting of a pair. of drums arranged onon posite sides of the boiler below the Water i adjacent the boiler,valved blow-off pipes leading from the bottoms of the drums, circulating.-pipes leading. from-the front ends ofthe drums to theboilersand provided With cut-oil? valves, return pipes leading from'therear ends of the drums to the mud ring of the boiler and provided withcut-off valves, and water supply pipes leading into the tops of thedrums and provided with cut-0E valves.

In testimony whereof I have hereunto set 15 my hand in presence of twosubscribing witnesses. 4

DANIEL N. BAXTER.
